It is sometimes suggested that when a practitioner writes up their research in third person style (the teacher-researcher interviewed the student', rather than 'I interviewed the student), this is dishonest as it attempts to present to present an objective account that underplays the researcher's intimate involvement in the research context, and so give the impression that the (teacher-)research was able to stand back and observe as an outsider.
Some new teacher-researchers do adopt this third-person style, and usually there is no intended dishonesty, but rather an attempt to emulate what they believe research writing is meant to be like.
The author once read an assignment from a trainee teacher offering an account of both an observation of a teacher's lesson and of how-at the end of the lesson-the observer approached the teacher and offered a rather critical evaluation of the teaching observed.
I was concerned about this assignment at two different levels. For one thing, the trainee was meant to have critiqued his own teaching and not that of one of the teachers working in his placement school.
